Basic design of propylene recovery unit

Abstract

Propylene, otherwise called Propene, is one of the most vital petrochemical feedstock created in the business sectors around the world. The by a wide margin biggest share of worldwide propylene yield around 66% is handled into polypropylene (PP). Interest for this plastic is anticipated to increment by 3.7% for every annum until 2021 and will, in this way, rule request improvement in the propylene advertise. Polypropylene is a standout amongst the most adaptable bundling materials. Different applications incorporate filaments, materials, vehicle parts, electric gadgets and family unit merchandise, and substantially more. The growing source for propylene production is from the refineries mainly from FCCU, coker and cracking units. In this thesis, a propylene recovery unit has been simulated based on the data obtained from Essar oil Ltd. The design criterion and objectives for the project were fixed from the findings obtained as a result of literature survey and the product requirement studies. A model for the propylene recovery unit was created in Aspen Hysys by using the Soave-RedlichKwong (SRK) as the fluid package. After completing the basic design of Propylene Recovery Unit (PRU) in Hysys, a yield of 99.58% by volume pure propylene was obtained which is 0.08% more than the value acquired from the simulation data received from Engineering India Ltd. (EIL). The study can be further continued by changing the fluid packages or by comparing the study with other licensors.
